HAND #1

That is a short stack that should either push or fold (if competent). and a 45/27 is limping w/ such a wide variety of junk...but it is most likely suited junk. could be a pair + FD, weird OESD, or smaller overpair than you.

If this is a competent/good short stack (i.e. understands the power of fold equity), then I would fold to the min raise because that suggests a monster & a good shorty would push w/ a draw for fold equity.

HAND #2 -

Clear call w/ an OESD + a pair on that board. the outs for your set may not be clean if you're worried abt villan having JJ (or worried abt an overpair since his 3bet calling range is probably wafer thin), but the outs for the OESD should be good...you've got both 8s so it's unlikely you're up against a made straight that is bigger than yours. plus you're getting almost 6:1 pot odds. easy call.

HAND #3

Why check turn w/ a FD on the board? I would have gone to value town on turn (1/2 PSB) & river (2/3 PSB).
